We study the implications of asymmetric dark matter on neutron stars. we
construct a "mixed neutron star" model composed of ordinary baryons and of
asymmetric dark matter baryons. We derive the general relativistic structure
equations for each specie, the equation for the mass within a given radius, and
the redshift as function of radius. We present one specific numerical model as
an illustrative example. In this example, the mass of the dark neutron equals
half that of the ordinary neutron. The main results are: a total mass of $3.74
M_{\odot}$, a total mass within the neutron-sphere equaling $1.56 M_{\odot}$,
the neutrons mass is $1.34 M_{\odot}$, the star radius is 31.9 km, the
neutron-sphere radius is 11.1 km, and the redshifts from the neutron-sphere and
from the star surface are 0.72, 0.25, respectively. We comment briefly on
possible astrophysical implications.
